France, Germany and the United Kingdom (the “E3”) wish to bring to the attention of the Security Council the status of Council resolution 2231 (2015) implementation prior to the final meeting of the Security Council before Termination Day.

The Director General of the International Atomic Energy Agency (IAEA) published two reports on 31 May which clearly show the dire status of the Iran nuclear issue. The report on Iran’s implementation of the Joint Comprehensive Plan of Action (JCPOA) lays out Iran’s extensive violations of its JCPOA commitments. IAEA now assesses that Iran’s uranium stockpiles have reached more than 8,600 kg of uranium and include 408.6 kg of uranium enriched up to 60 per cent. That is more than nine significant quantities – defined by IAEA as the approximate amount from which the possibility of manufacturing a nuclear explosive device cannot be excluded. As stated by the Director General in the report, Iran is the only State without nuclear weapons enriching to this level. This alone breaches four of Iran’s key JCPOA commitments: the enriched uranium stockpile limit (300 kg); the enrichment limit (3.67 per cent); use of the deep underground Fordow facility; and the development, manufacture and use of advanced centrifuges (which are also in use at Fordow). This is just one example of Iran’s failure to abide by its JCPOA commitments which extend much further: Iran has also installed new advanced centrifuge cascades during this period of reporting.

Iran’s obfuscation and lack of cooperation with IAEA on its verification and monitoring activities is highly concerning: for months now, the Agency has lost continuity of knowledge on several parts of Iran’s programme, including on the production and inventory of centrifuges. Today, the Agency is not able to provide assurance of the exclusively peaceful nature of Iran’s nuclear programme. This is all the more worrying in light of the Director General’s comprehensive report (GOV/2025/25), which lays out Iran’s multiple failures to implement its safeguards obligations.
